ABSTRACT: Newcastle disease virus (NDV) is not
considered as cause of serious disease in humans. But, recent data make it
clear that, under particular circumstances, it is indeed possible for NDV to
cause severe human respiratory disease. Newcastle Disease infection has been
reported in many bird species. Cormorants that inhabit at the Qinghai-Tibet
Plateau are mainly represented by Great Cormorant (Phalacrocorax carbo
sinensis), which is distributed mainly on the Qinghai Lake area. Cormorants
are considered as one of the main NDV-reservoir. We conducted the study for the
presence of antibodies to Newcastle disease virus by hemagglutination
inhibition test in yolks. We got 50% of seropositive yolks to Newcastle disease
virus. These results show that NDV circulates in the Qinghai Lake population of
cormorants. We first used the technique of detection of antibodies to Newcastle
disease virus in the egg yolk for study the circulation of the virus in
cormorants and demonstrated its effectiveness. We should carefully monitor
cases of pneumonia in the population of people living around the lake and
assess the causes of the disease.
